More than three decades on the line

The Beechcraft Model 18 was produced continuously from 1937 to November 1969, more than 32 years, which was a world record at the time. More than 9,000 aircraft were built. The model was developed in the mid-to-late 1930s, mainly as a compact business aircraft and regional airliner. The prototype made its maiden flight on 15 January 1937.

Uniform and civilian livery

In military service it received designations such as C-45 Expeditor, AT-7 Navigator and AT-11 Kansan. It was sold worldwide as a civilian executive, utility, cargo and passenger aircraft. In the early postwar years, the Beech 18 was the quintessential "business aircraft" and "feeder airliner."
